I am ready to finish my cherry table top. In the past I merely applied polyeurathane directly on the cherry and have been satisfied with the amber result as cherry ages overtime. There have been some cases of blotching and in this table top I want to minimize this risk. As I understand it, if I put on a coat of seal coat like unwaxed shellac first, it will control the blotching. Then the coats of poly would follow. Is this an accurate description of the sequence? There won’t be any issues of bonding between the shellac and polyeurathane in the long run?
